Pneumatic tire

A pneumatic tire comprising

• a tread having a tread surface that comes in contact with a ground;
• wherein the tread comprises a plurality of main grooves extending along a full circumference in a tire circumferential direction, and a plurality of lands partitioned by the main grooves;
• the plurality of lands include a first land;
• the first land comprises a plurality of circumferential grooves that extend in the tire circumferential direction and that are arrayed in a tire axial direction;
• the plurality of circumferential grooves are respectively arranged at portions in the tire circumferential direction of the first land;
• the plurality of circumferential grooves include a first circumferential groove which is arranged in inwardmost fashion in the tire axial direction, and a second circumferential groove which is arranged in outwardmost fashion in the tire axial direction;
• as viewed in a tire meridional section, an inner space area of the first circumferential groove is greater than an inner space area of the second circumferential groove,
• wherein the first land further comprises a plurality of slits which extend along the entire length in the tire axial direction of the first land, and a plurality of blocks which are partitioned by the plurality of slits;
• the plurality of blocks include a first block, and a second block which is arranged toward a first side in the tire circumferential direction of the first block;
• the plurality of slits include a first slit which is arranged between the first block and the second block, and a second slit which is contiguous with a second side in the tire circumferential direction of the first block;
• a first end at the first side in the tire circumferential direction of the first circumferential groove is arranged toward the second side in the tire circumferential direction from the first slit;
• a second end at the second side in the tire circumferential direction of the first circumferential groove is arranged toward the first side in the tire circumferential direction from the second slit;
• a first end at the first side in the tire circumferential direction of the second circumferential groove is arranged toward the first side in the tire circumferential direction from the first slit;
• and
• a second end at the second side in the tire circumferential direction of the second circumferential groove is arranged toward the first side in the tire circumferential direction from the second slit.
